connection of the cover or closure and its operating means.

Describing my invention more in detail, it is my object to provide a novel means My invention relates to a pumping and ejecting mechanism and process for removing the liquid content and gases, odors and the like from certain materials, such as arbage orother materials, such as used in hospitals after and resulting from surgical operations or other medical treatment; in short, any material which it is desired to be nor of all materials which have objectionable odors and are likely to produce contamination if exposed. to the atmosphere, it being dehydrated, reduced in bulk, and its odor or posslble to keep said materials for a long gases removed therefrom. time withoutthe slightest odor emanating To this end, my invention has for an ob ect erefrom; said materials may comprise garto provide a container having a cover probage, the hydrous or other materials resultvided with means for rendering the said g from surgical operations, medical container fluid tight, in which the materials treatments andthe like, such as the disposal tobedesiccated,reduced in bulk, dehydrated, i contamlnated gauze, in short, any maand its odors and gases removed therefrom, l l a g lml o healthare placed, a vacuum or pumping means, lo this end I provide a suitable container preferably in the form of a hydraulic ejec tor means, being associated with said container for subjecting the latter to vacuum conditions, means being also provided for breakin the vacuum and lifting said cover by mec anical means, said vacuum being preferably broken before said cover is lifted to facilitate the lifting thereof.

Further objects and advantages of my invention, as will hereinafter more fully appear, I attain by the novel process and mechanism described in the specification and illustrated on the drawings, forming :1. art of my application.

eference is had to the accompanying drawin s, in which similar reference characters enote similar parts. in the drawig. 1 is a vertical cross-sectional view of the apparatus comprising my invention and illustrating the manner in which the process is effected,

Fig. 2 is a vertical cross-s ctional view, taken on the line 2-.-2, Fig. 1, looking in the direction of the arrows,

Fig. 3 is an enlarged fragmentary crosssectional view, taken on the line 3-3, lookin in the direction of the arrows,

ig. 4 is a similar view of the top of the container, showing the mechanism in position just as the vacuum has been broken, with cover or closure read to be lifted,

Fig. 5 is a similar view s owing the cover or closure lifted, and

Fig. 6 is a fragmentary end view of the top of the container, illustrating the hinged otherwise formed as in practice preferred, said casing being providedwith a support 6 of any desired configuration and structure, said casing being preferably made of metal.

The casing 4 of the container 2 is provided with a cover 8 hinged to said casing in any suitable manner as by thehinge member 10, shaped as shown, and pivoted to the standards 12, associated in any preferred way with said casing, a pin 14 being used to pivot the member 10 to said standards.

The cover 8 is preferably shaped as shown and provided with an inturned port-ion to house the gasket or packing means 18, preferably made of rubber, so that when said. cover is closed under pressure a fluid tight joint with the casing a is had,.it being impossible for any odors to escape; In fact, it has been demonstrated in practice that the foulest material, such as decaying garbage, can be maintained therein for weeks without the slightest odor emanating therefrom. The casing 4 may be provided at its top with a curled portion 20 to engage the gasket \clear that the cover may be packed, and rendered fluid tight in any preferred manmy invention.

If desired, a separate and distinct container, such as the receptacle or pail 22, ro-

vided with the handle 24, may be us to house the materials to be desiccated, dehy- Q, comprising a casing 4, cast, stamped or,

and process for disposing in a sanitary mani to insure a fluid tight joint. While the structure just described insures ease of man ufacture with minimumexpense, it will be ner, and still remain within the province of I to break the vacuum in the casing 4 to facilitate the lifting of said cover. To this end said cover may be provided with a perforation or opening 30, and a closure means 32 of suitable form and material is provided to hold said perforation or opening closed, a

"fiat spring 34, being secured in any desired manner, as by rivets, 36, to the hinge member 10. See Figs. 1, 4 and 5.

The spring 34 holds the closure 32 in engagement with the hole or perforation 30,

and some means must be provided to lift said spring so that the vacuum in the casing 4 may be broken. Such a means is shown at 38, which means may be a bar, pipe, rod or other member, slotted at 40, in which slot a pin or cross rod 42 is positioned, said pin being secured in any desired way to the hinge member 10.

The operating means 38 is pivoted at 44 to a lever 46, pivoted at 48, to the standard 50 associated in an preferred manner, as

by rivets 52 to the bottom 54 of the casing 4, a foot pedal 56 being used to operate the lever 46. This structure comprises the com- 8 bined vacuum breaking and cover lifting means. I

The pumping or fluid ejecting means comprises a Venturi tube 58, housed in a suitable casing 60, preferably positioned near the bottom of the casing 4, said Venturi tube being preferably shaped as shown and in fluid connection with said casing by suitable pi e connections 62, the casing 4 being provided internally with a wire gauze 64 to prevent any solid materials from leaving said casing. The Venturi tube 58 has a connection 66 leading to, the sewer or some other convenient point of discharge, and the pipe 68 leads to a water supply, which may be the city water main, said connection 68 terminating in a suitable flow nozzle 70, projecting as shown into the .Venturi tube 58. See Fig. 3. Of course, suitable shut off valves may be rovided as desired. The operation 0 the mechanism and process should now be clear. The materials to. be deodorized, dehydrated and reduced in bulk having been placed in the receptacle and the cover 8 closed, the spring 34 cansso in the closure 32 to close the opening 30. ater is now turned on in the pipe 68, the flow of the fluid being indicated by the arrows in Fig. 3, and the air is exhausted from the container 2, as indicated by the arrows, II said water issuing from the nozzle 70 causing a depression at the contracted portion of the Venturi tube 58, the gases being conveyed with water to the sewer or some extraneous point. Only a small pressure flow of the Water is needed, and all odors are removed from the container.

To open the container, all that is necessary is to depress the pedal 56 with the foot, causing the operating means 38 to be lifted, the upper end of which, due to the slot 40, first lifting the spring 34, as shown by the arrows, said spring assuming the position shown in Fig. 4, lifting the closure 32 away from the hole 30 and breaking the vacuum in the container, a further movement of the operating means 38, through the hinge portion 10, causing the cover to be swung to the position shown in Fig. 5. The receptacle 22 may be removed from the container, and covered by the cover 26, and another receptacle substituted.

While I have thus described my invention with great particularity, it will be clear that the same may be modified throughout a wide range. I accordingly do not propose to be limited to the exact details of construction shown and described, but reserve the right in practice to make an and all modifications thereof that fall within the scope of the appended claims.
